No suggestions on the install, it's pretty staright forward. The hardest part I had was fishing the wire through the grommet in the firewall. A couple points after you get things hooked up; flip the switch to the "on" position before you throw it into 4wd. A easy way to tell if you are in 2-lo is that the 4wd light on the dash should be "off". If you are in 2-lo, and shut the truck off, and then restart, you will be in 4 lo, not 2-lo (check for the light on the dash). Those were the only things that had me baffled initially... Good luck.
